Some further clarity on our unique trx hashes queried to our platform, our initial and followup numbers on unique trx hashes queried were not accurate - apologies. Bitcoin addresses queried and Usd value and unique were accurate. This is as a result of our platform viewing each queried bitcoin address as a transaction from our point of view. November 2022 Total queried unique bitcoin address- circa 1.5m trxs Unique Bitcoin trx hashes queried- circa 500k USD value - circa 220m December 2022 Total queried unique bitcoin address- circa 1.7m trxs Unique Bitcoin trx hashes queried - circa 500k USD value - circa 200m There are further merchants and service providers who enable 0-conf on Bitcoin who are not working via our platform - I do not know their numbers but believe they are significant. 0-conf on Bitcoin with its understood risks is a significant use case.
